Plot Point Pattern on Linear Network

Plots a point pattern on a linear network. Plot method for the class "lpp" of point patterns on a linear network.

Keywords
hplot, spatial
Usage
## S3 method for class 'lpp':
plot(x, \dots, main, add = FALSE,
                   use.marks=TRUE, which.marks=NULL,
                   show.all = !add, show.window=FALSE,
                   do.plot = TRUE, multiplot=TRUE)
Arguments
x
Point pattern on a linear network (object of class "lpp").
...
Additional arguments passed to plot.linnet or plot.ppp.
main
Main title for plot.
add
Logical value indicating whether the plot is to be added to the existing plot (add=TRUE) or whether a new plot should be initialised (add=FALSE, the default).
use.marks
logical flag; if TRUE, plot points using a different plotting symbol for each mark; if FALSE, only the locations of the points will be plotted, using points().
which.marks
Index determining which column of marks to use, if the marks of x are a data frame. A character or integer vector identifying one or more columns of marks. If add=FALSE then the default is to plot all columns
show.all
Logical value indicating whether to plot everything including the main title and the window containing the network.
show.window
Logical value indicating whether to plot the window containing the network. Overrides show.all.
do.plot
Logical value determining whether to actually perform the plotting.
multiplot
Logical value giving permission to display multiple plots.
Details

The linear network is plotted by plot.linnet, then the points are plotted by plot.ppp.

Commonly-used arguments include:

  • colandlwdfor the colour and width of lines in the linear network
  • colsfor the colour or colours of the points
  • charsfor the plot characters representing different types of points
  • legendandleg.sideto control the graphics legend

Value

  • (Invisible) object of class "symbolmap" giving the correspondence between mark values and plotting characters.
